Troubleshooting

2.To adjust the Ribbon Shield (see Figure 5-2), temporarily move the ribbon and loosen the screw located on the left end of the Head-Support Plate, (do not remove the screw). This end of the shield can be adjusted up or down in order to even out the ribbon tension across the full width of the ribbon.

Note: The mount screws that secure the Ribbon Shield also secure the Head-Support Plate. When loosening these screws, be aware that both the shield and the plate may be affected.

3.Position the shield so that there is no rippling in the ribbon as it travels from the Ribbon Supply Hub. The ribbon should also be adjusted so that the tension is even across the entire width of the ribbon.

4.Once the Ribbon Shield is properly positioned, tighten the left screw that supports the Ribbon Shield to the Printhead Mount Assembly. Re-check the ribbon travel to make certain that the ribbon tension is even across the entire width of the ribbon.

5.Feed three or four labels and observe the ribbon as it travels from the Ribbon Supply Hub.

6.Feed the ribbon and paper out the front of the Printer together and check the ribbon for drifting. If the ribbon overlaps one edge of the paper stock, the ribbon and paper are not following the same path. In this case, the paper tracking may need to be re- adjusted. If there is no ribbon overlap, then continue.
